[The effect of quinidine monotherapy and combined therapy with digoxin on the central hemodynamics in patients with heart rhythm disorders].

The study was undertaken to examine 84 patients mainly with coronary heart disease and various cardiac arrhythmias. Quinidine monotherapy was found to normalize heart rate depending on its baseline values: it reduced heart rate in tachycardias and increased it in bradycardia. In patients with severe myocardial damage, especially in hypertension, quinidine decreased cardiac index, whereas total peripheral resistance increased.

[Dynamics of blood viscosity indices in patients with alcoholic myocardiodystrophy].

According to I. V. Strel'chuk's classification, 120 patients with alcoholic myocardiodystrophy induced by stage I-III chronic alcoholism were examined.

[Pathogenesis of diabetic lesions of the myocardium].

On the basis of both literature data and their own observations, the authors suggest the identification of various forms of diabetic cardiopathy in relation to the pathogenetic mechanisms of the development of this complication. The microangiopathic form of diabetic cardiopathy develops as a result of cardiac diabetic microangiopathy. Vegetoneuropathic cardiopathy arises secondary to the impairment of the cardiac performance neural regulation associated with damage to the parasympathetic and/or sympathetic innervation of the heart secondary to diabetic vegetoneuropathy.
